Justice Across Ages offers an attractive account of justice between the young and the old that brings together three notable principles of age-group justice: complete-lives equality, relational equality, and prudence. Yet, the book says little about the fact that many of us live longer than others, and the little it does say casts doubt on whether lifespan inequality threatens justice as construed by the three principles. This essay argues, instead, that theories of justice between the young and the old should (...) not dispense with a conception of justice between different longevity groups. It concludes that we must be sensitive to lifespan variations when designing policies to promote justice across age groups. (shrink)

The distinction between ‘relational' and ‘distributive’ equality has come to play an important role in discussions of equality and justice. But the nature of the distinction is not as clear as we might hope. In this regard, Juliana Bidadanure makes an interesting and important proposal: the two views involve differing kinds of temporal concern. The distributive approach, she suggests, is concerned with equality over people’s complete lives (diachronic equality), whereas the relational approach is concerned with egalitarian social relations at each (...) moment in time (synchronic equality). I argue that this suggestion, while insightful, is not entirely satisfactory. Both relational and distributive equality, I demonstrate, have diachronic and synchronic aspects. Nonetheless, they do so in distinctive ways. So, while the diachronic/synchronic distinction does not provide a clean cut between relational and distributive equality, examining the temporal aspects of each approach helps to illuminate their distinctiveness.
